In a practical application, the testing machine 2 can include a machine body 21, a control set 22 disposed on the machine body 21, and a plurality of probe sockets 23. Each of the probe sockets 23 includes a plurality of probes (not shown), and the probes of the probe sockets 23 are configured to be electrically connected to the chips C under test, and the control set 22 is configured to perform a related testing process to test the chips C (as shown in FIG. 8) under test through the probe sockets 23. In a practical application, the machine body 21 can include a structure (not shown) to be fixed with the chip tray kit 1, the machine body 21 or each of the probe sockets 23 can include a structure (not shown) to auxiliarily limit the chips C, but the present disclosure is not limited thereto. The control set 22 can be a circuit board, a microprocessor or a control circuit.

As shown in to FIG. 1, FIG. 3, and FIG. 8, the chip tray kit 1 can include a tray 11 and twenty four chip fixing members 12. The tray 11 includes twenty four tray thru-holes 111, and each of the tray thru-holes 111 penetrates through the tray 11. The quantity, the structure, and the arrangement of the tray thru-holes 111 included by the tray 11 are not limited to those shown in FIG. 1, FIG. 3, and FIG. 8. The quantity of the chip fixing members 12 corresponds to the quantity of the tray thru-holes 111. Each of the chip fixing members 12 is detachably fixed to the tray 11, and the chip fixing members 12 are correspondingly fixed in the tray thru-holes 111.

In a practical application, the chip tray kit 1 can further include a plurality of auxiliary fixing members 13, part of the auxiliary fixing members 13 are detachably fixed (e.g., in cooperation with a least one screw) to a side surface of the tray 11, and another part of the auxiliary fixing members 13 are detachably fixed to another side surface of the tray 11. In FIG. 3 and FIG. 4 of the present disclosure, each of the chip fixing members 12 can be fixed to the tray 11 through ten of the auxiliary fixing members 13, the two side surfaces of the tray 11 opposite to each other respectively have four auxiliary fixing members 13 and six auxiliary fixing members 13 disposed thereon, and the chip fixing member 12 can be fixed in the tray thru-hole 111 through the ten auxiliary fixing members 13. The structure and quantity of the auxiliary fixing members 13 used to fix one of the chip fixing members 12 to the tray 1 are not limited to those shown in FIG. 3 and FIG. 4.

Referring to FIG. 5 to FIG. 8, each of the chip fixing members 12 includes sixteen fixing thru-holes 121, sixteen chip accommodating slots 122, and a plurality of limiting structures 123. The quantity of the fixing thru-holes 121, the quantity of the chip accommodating slots 122, and the quantity of the limiting structures 123 of each of the chip fixing members 12 are not limited to those shown in FIG. 5 to FIG. 8. In each of the chip fixing members 12, each of the fixing thru-holes 121 penetrates through the chip fixing member 12, the chip accommodating slots 122 are in spatial communication with the fixing thru-holes 121, and each of the chip accommodating slots 122 is configured to carry one of the chips C under test. A plurality of electrical contacting portions (not shown, such as various types of pins) of the chips C disposed in the chip accommodating slots 122 are exposed from the chip fixing member 12, and the electrical contacting portions are configured to be connected to the probe sockets 23 so that the testing machine 2 (as shown in FIG. 1) can be electrically connected to the chips C.

Each of the limiting structures 123 is formed by a plurality of side walls forming the corresponding one of the chip accommodating slots 122 that extends toward the chip accommodating slot 122. The limiting structures 123 is the same chip accommodating slot 122 are configured to jointly limit a movement range of the chip C in the chip accommodating slot 122 to prevent the chip C in the chip accommodating slot 122 from leaving the chip accommodating slot 122. In the present embodiment, the chip C in the accommodating slot 122 is limited by four limiting structures 123, but the quantity, the position, and the structure of the limiting structures 123 are not limited to those shown in FIG. 5 to FIG. 8. Naturally, the limiting structures 123 do not prevent the chip C in the accommodating slot 122 from being electrically connected to the probe sockets 23 of the testing machine 2.

Referring to FIG. 7, in a practical application, each of the chip fixing members 12 can include a guide structure 124 therein, and the guide structure 124 can be an inclined surface that is inclined toward the chip accommodating slot 122. Through the design of the guide structure 124, in a process where the chip C is disposed into the chip accommodating slot 122 through the fixing thru-hole 121, even if a placement position of the chip C is slightly deviated, the chip C can be guided by the guide structure 124 to be successfully disposed into the chip accommodating slot 122.

According to the above, since the chip fixing members 12 are detachably fixed to the tray 11, a user can selectively change the chip accommodating slots 122 and the fixing thru-holes 121 having different structures and dimensions of the chip fixing members 12 according to the type, the structure, and the dimension of the chips C under test.

Referring to FIG. 5 and FIG. 6, in a preferable application, the chip tray kit 1 can further include a plurality of elastic members 14. One end of each of the elastic members 14 is fixed to a first accommodating slot 1121 of a plurality of side walls 112 forming each of the tray thru-holes 111, and another end of each of the elastic members 14 is correspondingly disposed in a second accommodating slot 1251 of a plurality of side walls 125 of the chip fixing member 12. In an embodiment of the present disclosure, each of the chip fixing members 12 is substantially in a rectangular structure, at least one of the elastic members 14 can be disposed between each of the side walls 125 of the chip fixing member 12 and each of the side walls 112 forming the tray thru-hole 111.

When the chip fixing members 12 are fixed to the tray thru-holes 111, each of the elastic members 14 is in a pressed state, and an elastic force generated by each of the elastic members 14 being pressed pushes the chip fixing member 12. Therefore, the chip fixing members 12 can be stably disposed in the tray thru-holes 111. The elastic members 14 are disposed between the side walls 125 of the chip fixing members 12 and the side walls 112 forming the tray thru-holes 111, and the auxiliary fixing members 13 are fixed on two opposite wide surfaces of the tray 11. Therefore, when the auxiliary fixing members 13 are detached from the tray 11 by a user, the chip fixing members 12 can still remain disposed on the tray 11 due to the elastic members 14 pushing the chip fixing members 12, thereby preventing the chip fixing members 12 from falling off when the auxiliary fixing members 13 are detached from the tray 11. In addition, through the arrangement of the elastic members 14, when the chip tray kit 1 is fixed to one side of the testing machine 2 (as shown in FIG. 1), the chip fixing members 12 move slightly relative to the tray 11. Therefore, the chips C carried by the chip fixing members 12 can be easily connected to the probe sockets 23 (as shown in FIG. 2) of the testing machine 2.

Referring to FIG. 1 and FIG. 5 to FIG. 9, the chip tray kit 1 can further include twenty four auxiliary insertion members 15. The quantity of the auxiliary insertion members 15 is corresponding to the quantity of the chip fixing members 12, but the quantity of the auxiliary insertion members 15 is not limited to that shown in FIG. 1 and FIG. 5 to FIG. 9. Each of the auxiliary insertion members 15 is detachably disposed on one side of the corresponding one of the chip fixing members 12.

Each of the auxiliary insertion members 15 includes a main body 151 and a plurality of protrusions 152. Each of the protrusions 152 protrudes from one side of the main body 151, and the quantity of the protrusions 152 corresponds to the quantity of the fixing thru-holes 121 of each of the chip fixing members 12. Each of the chip fixing members 12 can further include a plurality of accommodating recesses 126, and each of the accommodating recesses 126 is in spatial communication with the corresponding one of the chip accommodating slots 122. A diameter W1 of the accommodating recess 126 is greater than a diameter W2 of the chip accommodating slot 122, and the accommodating recesses 126 are configured to accommodate the protrusions 152 of the auxiliary insertion members 15.

Each of the auxiliary insertion members 15 includes an insertion thru-hole 153 penetrating through the main body 151 and the protrusions 152. A diameter W3 of the insertion thru-hole 153 is greater than an outer diameter W4 of a contacting portion 421 of the pressing member 42 (as shown in FIG. 18 and will be described as follows), and a portion of the contacting portion 421 is configured to penetrate through the insertion thru-hole 153 and is exposed from a side of the auxiliary insertion member 15 (as shown in FIG. 18). The diameter W3 of the insertion thru-hole 153 is less than the diameter W2 of the chip accommodating slot 122. A height of the protrusion 152 is substantially equal to a depth of the accommodating recess 126. When the protrusion 152 is arranged in the accommodating recess 126, the main body 151 of the auxiliary insertion member 15 correspondingly abuts against a top surface 128 (as shown in FIG. 8) of the chip fixing member 12.

Referring to FIG. 7 and FIG. 8, each of the protrusions 152 can include a plurality of guide inclined surfaces 1521 to allow the protrusion 152 to swiftly and correctly enter the fixing thru-hole 121. The guide inclined surfaces 1521 are configured to enable the protrusion 152 to enter the fixing thru-hole 121 more easily. Referring to FIG. 8, in a practical application, when the chip C is disposed in the chip accommodating slot 122 and the protrusion 152 is arranged in the accommodating recess 126, a gap G is formed between the protrusion 152 and a surface C1 of the chip C, and the protrusion 152 is not in contact with the surface C1 of the chip C. When the chip fixing members 12 and the auxiliary insertion members 15 are fixed to the tray 11, the chips C disposed in the chip accommodating slots 122 of the chip fixing members 12 are jointly limited by the chip fixing members 12 and the auxiliary insertion members 15, such that it is difficult for the chips C to be detached from the chip fixing members 12.

The present disclosure does not limit the manner in which each of the auxiliary insertion members 15 is detachably disposed on one side of the corresponding one of the chip fixing members 12. Any manner that can allow each of the auxiliary insertion members 15 to be detachably disposed on one side of the corresponding one of the chip fixing members 12 falls within the scope of the present disclosure. For example, in one embodiment of the present disclosure, each of the auxiliary insertion members 15 and each of the chip fixing members 12 can be disposed in the tray thru-hole 111 of the tray 11 together, and the auxiliary fixing members 13 mentioned above can limit a movement range of each of the auxiliary insertion members 15 and each of the chip fixing members 12 relative to the tray 11. In other words, each of the auxiliary insertion members 15 and each of the chip fixing members 12 are fixed in the tray thru-hole 111 of the tray 11 through the auxiliary fixing members 13.

According to the above, as shown in FIG. 1, FIG. 5, FIG. 6, and FIG. 9 to FIG. 12, in a preferable embodiment, the chip tray kit 1 can further include a plurality of quick release assemblies 16. At least one of the quick release assemblies 16 is arranged between each of the auxiliary insertion members 15 and the corresponding one of the chip fixing members 12, and each of the auxiliary insertion members 15 can be quickly mounted to or detached from one side of the chip fixing member 12 through the at least one of the quick release assemblies 16. For example, in each of the chip fixing members 12, two of the quick release assemblies 16 can be disposed on the chip fixing member 12, and each of the quick release assemblies 16 can include two limiting members 161 and two elastic members 162. Each of the chip fixing members 12 can further include a recess 127, one end of each of the two elastic members 162 is fixed to a side wall forming the recess 127, another end of each of the two elastic members 162 is fixed to one of the limiting members 161, and the two limiting members 161 of each of the quick release assemblies 16 are disposed in one of the recesses 127.

Each of the limiting members 161 can be pushed to move in the corresponding one of the recesses 127 to correspondingly press the elastic member 162 connected thereto, and the pressed elastic member 162 correspondingly generates an elastic returning force. When the limiting member 161 is no longer pushed, the elastic returning force generated by the elastic member 162 being pressed allows the limiting member 161 to return to a position where the limiting member 161 is not pushed. When the two limiting members 161 are disposed in the recess 127, a gap P is formed between the two limiting members 161.

Each of the limiting members 161 can include an engaging slot 1611, each of the engaging slots 1611 separates the limiting member 161 into a pushing portion 16A and an engaging portion 16B, the pushing portion 16A has a guide inclined surface 16A1 at an end thereof opposite to the elastic member 162, and the engaging portion 16B has an engaging inclined surface 16B1 at an end thereof facing toward the pushing portion 16A.

Referring to FIG. 10, each of the auxiliary insertion members 15 can have a thru-hole 155 formed thereon and can have two engaging members 154 disposed thereon, the two engaging members 154 are arranged at two ends of the thru-hole 155, and each of the engaging members 154 has an engaging inclined surface 1541 at an end thereof opposite to the thru-hole 155. The thru-hole 155 of each of the auxiliary insertion members 15 is configured to provide an insertion member R to insert therein. The insertion member R is configured to push the two limiting members 161 disposed on the chip fixing member 12. In a practical application, the insertion member R can be fixed to a related robotic arm configured to fix the auxiliary insertion member 15 to the chip fixing member 12.

Referring to FIG. 10 and FIG. 11, a process where the auxiliary insertion member 15 is in cooperation with the insertion member R and is to be fixed to the chip fixing member 12 can be exemplified as follows. First, the insertion member R penetrates through the thru-hole 155 of the auxiliary insertion member 15 and enters into the gap P between two limiting members 161. Since an outer diameter W4 of the insertion member R is greater than a width of the gap P, when the insertion member R enters the recess 127, the insertion member R pushes the pushing portions 16A of the two limiting members 161, and each of the limiting members 161 moves accordingly toward the corresponding one of the elastic members 162, such that each of the elastic members 162 is pressed and elastically deformed.

According to the above, as shown in FIG. 11, when an end of the insertion member R abuts against a bottom portion forming the recess 127, each of the engaging members 154 is disposed in the engaging slot 1611 of the corresponding one of the limiting members 161, the engaging inclined surface 1541 of each of the engaging members 154 faces toward the engaging inclined surface 16B1 of the engaging portion 16B of the adjacent limiting member 161, and each of the engaging inclined surfaces 1541 is not in contact with the adjacent engaging inclined surface 16B1. Afterwards, as shown in FIG. 12, when the insertion member R is removed from the recess 127, the elastic returning forces generated by the two elastic members 162 in the recess 127 being pressed allow the two limiting members 161 to move toward each other. Finally, the engaging inclined surface 16B1 of the engaging portion 16B of each of the limiting members 161 abuts against the engaging inclined surface 1541 of the adjacent engaging member 154, and the auxiliary insertion member 15 is accordingly engaged with and fixed to the chip fixing member 12.

Referring to FIG. 12, when the auxiliary insertion member 15 is fixed to the chip fixing member 12 through the engaging members 154 and the quick release members 16, a structure (e.g., a related robot arm) can allow the insertion member R to penetrate through the thru-hole 155 of the auxiliary insertion member 15 and enter into the gap P between the two limiting members 161 to push the two limiting members 161. At this time, the two limiting members 161 change from a state shown in FIG. 12 to a state shown in FIG. 11. In the state shown in FIG. 11, the engaging inclined surface 16B1 of each of the limiting members 161 is no longer in contact with the engaging inclined surface 1541 of the adjacent engaging member 154. The structure (e.g., the related robot arm) can hold the auxiliary insertion member 15 and pull out the auxiliary insertion member 15 in a direction away from the chip fixing member 12 so as to separate the auxiliary insertion member 15 and the chip fixing member 12.

Referring to FIG. 3 and FIG. 5, it is worth mentioning that in an embodiment of the present disclosure, each of the auxiliary insertion members 15 is fixed to the chip fixing member 12 through the quick release assemblies 16, and each of the auxiliary insertion members 15 can have a plurality of avoidance holes 156 formed thereon. Each of the avoidance holes 156 is configured to avoid the auxiliary fixing member 13 so that the auxiliary fixing members 13 do not limit the movement range of the auxiliary insertion member 15.

Referring to FIG. 1, FIG. 13 and FIG. 16, the lid 3 can include a main body 31 and a conduction structure 32, one side of the main body 31 recesses to form an accommodating slot 311, the conduction structure 32 forms on one side of the main body 31, and the conduction structure 32 is arranged in the accommodating slot 311. A plurality of pressing assemblies 4 are disposed on the lid 3, and each of the pressing assemblies 4 is arranged in the accommodating slot 311 of the lid 3. It should be noted that in FIG. 16 of the present embodiment, the pressing assemblies 4 protrude from one end of the lid 3, but the present disclosure is not limited thereto. In other embodiments, the pressing assemblies 4 can be provided to not protrude from the lid 3, and the pressing assemblies 4 are completely arranged in the accommodating slot 311 of the lid 3. In other words, a sum of a thickness of the conduction structure 32 and a height of each of the pressing assemblies 4 can be greater than, equal to, or less than a depth of the accommodating slot 311 of the lid 3.

The lid 3 is configured to cover a side of the tray 11. When the lid 3 covers the side of the tray 11, the pressing assemblies 4 disposed on the lid 3 correspondingly press the surfaces C1 (as shown in FIG. 18) of the chips C in the chip fixing members 12 disposed on the tray 11. In other embodiments, when the lid 3 covers the side of the tray 11, the pressing assemblies 4 cannot be in contact with the chips C, until air in an enclosed space jointly defined by the lid 3 and the tray 11 is suctioned away, such that the pressing assemblies 4 press the surfaces C1 of the chips C. The dimension and the structure of the lid 3 and the quantity of the pressing assemblies 4 disposed on the conduction structure 32 of the lid 3 are not limited to those shown in FIG. 1, FIG. 13 and FIG. 16.

In a practical application, the lid 3 and the tray 11 can respectively include a plurality of guide structures 33 and a plurality of guide structures 113 that are configured to be engaged with each other. For example, each of the guide structures 33 of the lid 3 can include a blind hole, each of the guide structures 113 of the tray 11 can be a column structure, and when the lid 3 covers the side of the tray 11, the column structures of the tray 11 would be engaged with the blind holes of the lid 3. Through the design of the guide structures 33 of the lid 3 and the guide structures 113 of the tray 11, the lid 3 can swiftly and correctly cover the side of the tray 11 so that each of the pressing assemblies 4 can be swiftly and correctly arranged on one side of the corresponding one of the chips C in the chip accommodating slot 122. The quantity and structure of the guide structures 33 of the lid 3 and the guide structures 113 of the tray 11 are not limited to those shown in FIG. 1, FIG. 16, and FIG. 17.

Referring to FIG. 13 to FIG. 18, each of the pressing assemblies 4 includes a base seat 4, a pressing member 42, and two elastic members 43. In the present embodiment, sixteen pressing assemblies 4 share one of the base seats 41, but the present disclosure is not limited thereto. In other embodiments, the pressing assemblies 4 can be provided to not share the same base seat 41. The base seats 41 can be detachably fixed to the conduction structure 32 of the lid 3. In other embodiments, the base seats 41 and the conduction structure 32 can be a one-piece structure. In an embodiment of the present disclosure, the base seats 41 are detachably fixed to the lid 3, and the pressing assemblies 4 can be easily changed and maintained by technical personnel.

Each of the pressing members 42 includes the contacting portion 421 and an abutting portion 422. The contacting portion 421 includes a contacting surface 4211, the outer diameter W4 of the contacting portion 421 is less than the diameter W3 (as shown in FIG. 8) of the insertion thru-hole 153, a portion of the contacting portion 421 is configured to extend into the thru-hole 153 (as shown in FIG. 18), and the contacting surface 4211 is configured to press the surface C1 of the chip C. Primarily, the contacting portions 421 are configured to press the surfaces C1 of the chips C so that the chips C can be stably connected to the testing machine 2 (as shown in FIG. 1). Therefore, when the chips C are tested by the testing machine 2, an issue of the chips C separating from the probe sockets 23 (as shown in FIG. 2) can be avoided.

In each of the pressing members 42, the abutting portion 422 is connected to the contacting portion 421, and the abutting portion 422 is configured to limit a movement range of the pressing member 42 relative to the auxiliary insertion member 15 so as to prevent the contacting portion 421 from overly pressing on the chip C. As shown in FIG. 18, when the lid 3 covers the side of the tray 11, the abutting portion 422 of each of the pressing members 42 is arranged at one side of the auxiliary insertion member 15, the contacting portion 421 of the pressing member 42 is correspondingly arranged in the insertion thru-hole 153, and the contacting surface 4211 is correspondingly arranged at one side of the surface C1 of the chip C.

Two ends of each of the elastic members 43 are fixed to one of the base seats 41 and one of the pressing members 42. When the contacting surface 4211 of one of the pressing members 42 is in contact with the surface C1 of the chip C and the surface C1 is uneven, at least one of the elastic members 43 is in a pressed state, and the elastic returning force generated by the elastic member 43 being pressed allows the contacting surface 4211 to be tightly in contact with the surface C1 of the chip C. The quantity of the elastic members 43 included in each of the pressing assemblies 4 is not limited to two. In other embodiments, each of the pressing assemblies 4 can include one elastic member 43 or at least three elastic members 43.

As shown in FIG. 14 and FIG. 15, in a practical application, the elastic member 43 can be a compression spring. Each of the pressing assemblies 4 can include two compression springs (i.e., elastic members 43), and each of the pressing assemblies 4 can further include two guide members 44 and two fixing kits 45. The abutting portion 422 of the pressing member 42 can include two first recesses 4221, each of the base seats 41 can include two second recesses 411, each of the first recesses 4221 faces toward one of the second recesses 411, and two ends of each of the compression springs are respectively engaged with one of the first recesses 4221 and one of the second recesses 411.

The abutting portion 422 of each of the pressing members 42 can further include two penetrating holes 4222, each of the penetrating holes 4222 is in spatial communication with the corresponding one of the first recesses 4221, the two fixing kits 45 are fixed in the two penetrating holes 4222, each of the fixing kits 45 includes a penetrating hole 451, one end of each of the guide members 44 is fixed to one of the base seats 41, and another end of each of the guide members 44 penetrates through the penetrating hole 451 of the corresponding one of the fixing kits 45. When each of the pressing members 42 moves relatively to the base seat 41, each of the fixing kits 45 can move relative to the corresponding one of the guide members 44, and the two guide members 44 and the two fixing kits 45 can jointly limit a movement direction of each of the pressing members 42 relatively to the base seat 41. Through the two guide members 44 and the two fixing kits 45, each of the pressing members 42 can be effectively limited to substantially move in a direction perpendicular to an axis L (as shown in FIG. 18) of a surface of the base seat 41. Therefore, when each of the pressing members 42 presses the surface C1 of the chip C, the contacting portion 421 of the pressing member 42 would be in contact with the surface C1 of the chip C through the overall contacting surface 4211.

As shown in FIG. 14, each of the pressing assemblies 4 can further include at least one fixing structure 46 and at least one limiting member 47. The limiting member 47 is detachably fixed to the fixing structure 46, a portion of the limiting member 47 abuts against the abutting portions 422 of the pressing members 42, and the limiting member 47 and the fixing structure 46 are configured to jointly limit the movement range of the pressing members 42 relative to the base seat 41. For example, each of the base seats 41 can include twenty four fixing structures 46, every four of the twenty four fixing members 46 are arranged in a row and disposed on the base seat 41, every six of the fixing structures 46 and two of the limiting members 47 jointly limit four of the pressing members 42, and twenty-four of the fixing structures 46 are in cooperation with eight of the limiting members 47 so that sixteen of the pressing members 42 are disposed on the base seat 41. Each of the fixing structures 46 can include a screwing hole 461, each of the limiting members 47 includes three thru-holes 471, and three screws S can be in cooperation with three of the fixing structures 46 and three thru-holes 471 of one of the limiting members 47 so that one of the limiting members 47 is fixed to three of the fixing structures 46, and one of the limiting members 47 correspondingly presses the abutting portions 422 of four of the pressing members 42.

In a practical application, each of the limiting members 47 can further include an accommodating notch 472 configured to accommodate a portion of the contacting portion 421. In FIG. 14 of the present embodiment, one of the limiting members 47 abuts against the abutting portions 422 of four of the limiting members 47 at the same time. Therefore, the limiting members 47 can correspondingly include four accommodating notches 472, and each of the four accommodating notches 472 correspondingly accommodates a portion of the contacting portion 421 of the four limiting members 47. Through the design of the accommodating notches 472, the movement direction of each of the pressing members 42 relative to the base seat 41 can be auxiliarily limited, and each of the pressing members 42 substantially moves in the direction perpendicular to the axis L (as shown in FIG. 18) of the base seat 41.

In an embodiment of the present disclosure, each of the pressing assemblies 4 has the guide members 44, each of the limiting members 47 can correspondingly include at least one avoidance thru-hole 473, and each of the avoidance thru-holes 473 are configured to be penetrated by one of the guide members 44. In other words, when each of the pressing members 42 moves toward one of the base seats 41, a portion of each of the guide members 44 penetrates through one of the avoidance thru-holes 473. The structure of the avoidance thru-holes 473 is not limited to that shown in FIG. 14.

Referring to FIG. 1, FIG. 13, and FIG. 16 to FIG. 18, the temperature adjusting device 5 can be connected to the pressing assemblies 4 through the lid 3. The temperature adjusting device 5 is configured to allow a temperature of each of the pressing members 42 to reach a predetermined temperature. Through the temperature adjusting device 5, when the chips C disposed on the chip fixing members 12 are connected to the testing machine 2 and tested by the testing machine 2, the pressing members 42 reaching the predetermined temperature press the surfaces C1 (as shown in FIG. 8) of the chips C (as shown in FIG. 8). In this way, the chips C can be tested in an environment having the predetermined temperature. In a preferable embodiment, each of the pressing members 42 can be made of a metal material having a high thermal conductivity.

In a conventional chip testing operation, a plurality of chips are disposed and tested in a huge freezer or an oven. Since the temperatures of different areas in the freezer or the oven are not exactly the same, the chips cannot be performed with the chip testing operation in the same temperature. Therefore, a testing result is not reliable. In contrast, when the chips C are tested by the testing machine 2 of the chip testing apparatus A of the present disclosure, the contacting surface 4211 of each of the pressing members 42 having the predetermined temperature can allow the testing machine 2 to press the surface C1 of the chip C. Therefore, the chips C can be tested substantially in the same temperature.

In a practical application, the temperature adjusting device 5 can allow the temperature of each of the pressing members 42 to reach the predetermined temperature in any manner according to practical requirements, and the present disclosure is not limited thereto. For example, the temperature adjusting device 5 can be connected to the conduction structure 32 of the lid 3, each of the base seats is fixed to the conduction structure 32, the temperature adjusting device 5 can allow a temperature of the conduction structure 32 to increase or decrease, and the conduction structure 32 can mutually transfer heat with the pressing members 42 through the base seats 41 and the elastic members 43 so that the temperature of each of the pressing members 42 reaches the predetermined temperature. The conduction structure 32 mentioned herein is a structure made of a material having a high thermal conductivity. In an embodiment of the present disclosure, the main body 31 of the lid 3 and the conduction structure 32 are formed as a one-piece structure, and the temperature adjusting device 5 and the pressing assemblies 4 mutually transfer heat through the lid 3. In an embodiment of the present disclosure, the main body 31 of the lid 3 and the conduction structure 32 are not formed as a one-piece structure, and the temperature adjusting device 5 can be directly connected to the conduction structure 32.

In one embodiment of the present disclosure, the conduction structure 32 can internally include at least one fluid channel (not shown), and the temperature adjusting device 5 is configured to provide a fluid into the fluid channel so that the temperature of the conduction structure 32 increases or decreases. The fluid can be various types of high-temperature fluids or low-temperature fluids. In one embodiment of the present disclosure, the temperature adjusting device 5 can include a temperature controller (not shown) and a heating coil (not shown), the temperature controller is electrically connected to the heating coil, the heating coil is disposed in the conduction structure 32, and the temperature controller is configured to drive the heating coil to be operated so that the temperature of the conduction structure 32 increases. In an embodiment of the present disclosure, the temperature adjusting device 5 includes the temperature controller, the temperature adjusting device 5 can further include a cooling chip (not shown), the temperature controller is electrically connected to the cooling chip, the cooling chip is disposed in the conduction structure 32, the temperature controller is configured to drive the cooling chip to be operated so that the temperature of the conduction structure 32 decreases. In a practical application, both the cooling chip and the heating coil can be disposed in the conduction structure 32 at the same time, and the present disclosure is not limited thereto.

Referring to FIG. 14, each of the pressing assemblies 4 can further include a heat conduction member 48 so that the temperature of the pressing member 42 can easily reach the predetermined temperature. The heat conduction members 48 are arranged between the pressing members 42 and the base seats 41, the heat conduction members 48 are connected to the pressing members 42 and the base seat 41, and the heat conduction members 48 are configured to facilitate the heat to be transferred between the pressing members 42 and the base seat 41. Each of the heat conduction members 48 can include two elastic arms 481, and an end of one of the elastic arms 481 is connected to an end of the other one of the elastic arms 481. When the pressing members 42 move toward the base seat 41, the two elastic arms 481 are pressed by the pressing members 42 and are elastically deformed. When the pressing members 42 move away from the base seat 41, an elastic returning force generated by each of the elastic arms 481 being pressed allows the elastic arms 481 to return to an unpressed state. In this way, whether the pressing members 42 are static or moving relative to the base seat 41, the heat between the pressing members 42 and the conduction structure 32 can be preferably transferred by the heat conduction member 48. It is worth mentioning that the guide members 44 and the fixing kits 45 mentioned above can be also made of a material having a high thermal conductivity, and the guide members 44 and the fixing kits 45 can be also used to facilitate the heat to be transferred between the pressing members 42, the base seat 41, and the conduction structure 32.

Referring to FIG. 1 and FIG. 16 to FIG. 19, in a practical application, the chip testing apparatus A can further include an air suction device 6, a transferring device 7, and a processing device 8. The processing device 8 is electrically connected to the testing machine 2, the air suction device 6, and the transferring device 7, and the processing device 8 can control the testing machine 2, the air suction device 6, and the transferring device 7 to be operated. The processing device 8 can be various types of computers or servers.

The transferring device 7 is connected to the lid 3, and the transferring device 7 can move the lid 3 toward or away from the tray 11. The transferring device 7 mentioned herein is primarily configured to move the lid 3 and the tray 11 toward or away from each other. Therefore, in other embodiments, the transferring device 7 can be connected to the tray 11, and the transferring device 7 can move the tray 11 toward or away from the lid 3.

When the transferring device 7 moves the lid 3 toward the tray 11, the lid 3 covers one side of the tray 11, and one side of the tray 11 opposite to the lid 3 is fixed to the testing machine 2. The contacting surface 4211 of each of the pressing members 42 abuts against the surface C1 of the chip C, one side of the chip C is connected to the probe socket 23 of the testing machine 2, and the lid 3, the chip fixing member 12, the tray 11, and the chips C jointly define an enclosed space SP. At this time, the processing device 8 controls the air suction device 6 to suction air in the enclosed SP so that the enclosed space SP is in a negative pressure state.

It is worth mentioning that the chip testing apparatus A can further include a detector (not shown), the detector is electrically connected to the processing device 8, the detector is configured to detect whether the lid 3 covers the side of the tray 11, and the processing device 8 controls the air suction device 6 to be operated when the processing device 8 determines that the lid 3 already covers the side of the tray 11 according to a detecting result of the detector.

Since the air suction device 6 suctions away air in the enclosed space SP, and the enclosed space SP is in the negative pressure state, the air suction device 6 can effectively prevent a temperature inside of the enclosed space SP from being affected by the environment outside of the enclosed space SP. Moreover, a humidity of the enclosed space SP can also be effectively controlled, thereby effectively preventing condensation from occurring on the surface C1 of the chip C.

Referring to FIG. 8 and FIG. 18, the diameter W3 of the insertion hole 153 of each of the auxiliary insertion member 15 is less than the diameter W2 of the chip accommodating slot 122. Therefore, when the enclosed space SP is converted from the negative pressure state to a normal pressure state, and the transferring device 7 moves away from the tray 11, if the chip C adheres to the pressing member 42, the chip is pushed by an end of the protrusion 152 of the auxiliary insertion member 15 near the chip accommodating slot 122 to be separated from the contacting portion 421 when the contacting portion 421 leaves the auxiliary insertion member 15 along the thru-hole 153. In other words, since the auxiliary insertion members 15 are disposed on the tray 11, and the diameter W3 of the insertion hole 153 is less than the diameter W2 of the chip accommodating slot 122, it can be ensured that the chips C adhere to the contacting portions 421 when the lid 3 and the pressing members 4 move away from the tray 11.

When the chip testing apparatus A mentioned above of the present disclosure is manufactured and sold, the chip testing apparatus A can include the testing machine 2, the lid 3, the pressing assemblies 4, the temperature adjusting device 5, and the processing device 8, but the present disclosure is not limited thereto. In other embodiments, when the chip testing apparatus A of the present disclosure is manufactured and sold, it can further include at least one of the chip tray kit 1, the air suction device 6, and the transferring device 7. In addition, the chip tray kit 1 of the present disclosure can also be independently manufactured and sold.

Referring to FIG. 19, FIG. 19 is a sectional view of the pressing assembly of another embodiment of the present disclosure. The difference between the pressing assembly of the present embodiment and the pressing assembly of the previous embodiments is that the heat conduction member 48 can be in a column structure, an end of the heat conduction member 48 is fixed to a recess 423 of the pressing member 42, an end of the heat conduction member 48 is movably disposed in an accommodating slot 412 of the base seat 41, and another end of the heat conduction member 48 is fixed to the pressing member 42. When the pressing member 42 moves relatively to the base seat 41, the heat conduction member 48 correspondingly moves in the accommodating slot 412 of the base seat 41, the heat conduction member 48 is in contact with the side walls forming the accommodating slot 412 at any time, and the temperature adjusting device 5 and the pressing members 42 mutually transfer heat through the base seat 41 and the heat conduction member 48 in the column structure.
